3.5 Amp UltraSafe Battery Charger and Maintainer

The G3500 is a portable and automatic battery charger. It can be used for both 6V and 12V lead-acid and 12V lithium-ion batteries. The G3500 is designed for charging cars, boats, RVs, SUVs, diesel trucks, motorcycles, ATVs, snowmobiles, personal watercraft, lawn mowers, and much more. It can be used as a battery maintainer to keep both starter and deep-cycle batteries fully charged. It also monitors battery activity for safe and efficient charging without any overcharge. The G3500 is complete with a built-in battery desulfator in order to rejuvenate underperforming batteries.

Ultimate versatility.

Seven battery chargers in one.

Other brands require a separate battery charger for 12V charging, for AGM batteries, for 6V charging, for cold conditions, for lithium-ion batteries, and yet another for battery desulfation. With our versatile multi-purpose battery chargers, as your needs and vehicles change, your charger won't. With a simple push of a button, you'll have the power to switch between various charging modes within one, complete battery charger. And it's equipped with a progressive repair method for recovering heavily sulfated and weak 12-volt batteries.

12V Small Mode

Designed for charging (900mA) smaller battery applications that could be harmed by too much current. Both Small Norm and Cold/AGM settings are perfect for Motorcycles, ATVs, and more.

CANbus enabled.

Charge batteries directly from the 12-volt port.

CANbus electrical systems found on BMW, Ducati, Triumph and Harley-Davidson motorcycles disable the 12-volt charging port when the ignition is off. Recharging requires the ignition to be on, or direct connection to the battery. With CANbus enabled technology, our chargers send a unique voltage signal that automatically opens, and allows charging through the 12-volt accessory port.

5 Year Warranty.

Our battery chargers are built to last. That's why we back it up with an unbeatable warranty, combined with unparalleled customer service.

Advanced diagnostics.

Battery charging with intelligence.

Smart battery chargers can be frustrating. It won't simply begin charging if it detects a weak or damaged battery, or force charging if it detects an unsafe or abnormal charging condition. However, prevention is just one aspect. Understanding and finding a solution is just as critical. Welcome to Advanced Diagnostics, which analyzes battery feedback and display a particular error pattern if a problem is detected. Each flash pattern tells you what's wrong, and how to quickly fix it.Single Flash: Battery will not hold a charge and should be checked by a professional.Double Flash: Possible battery short, and should be verified by a professional.Triple Flash: Battery voltage is too high for the selected charge mode. Double check the battery matches the charge mode.Error LED Solid Red: Reverse polarity. Reverse the connections to the battery. Standby LED Solid Orange: Battery voltage is too low for the battery charger to detect the battery.

Battery Charging vs. Battery Maintenance.

Which battery charger is right for you?

Selecting the proper battery charger depends on your needs. Do you need to recharge a dead battery entirely, or just keep a battery at full charge? Battery charging means you need to recharge a dead battery fully, whereas battery maintenance requires a mere trickle charge. Most battery chargers perform both functions, but understanding their limits and the amount of time to recharge depends on the size of the battery and vehicle. The G3500 is designed for charging smaller applications, like a motorcycle, ATV, snowmobile, or lawn and gardening equipment. It's also a perfect battery maintainer for a car, boat, RV, or truck. The charging time chart not only helps you determine how long it will take to recharge, but also its limits between battery charging and battery maintenance.Why maintain your batteries?

Efficient design.

Compact, yet powerful battery charger.

A mix of electrical engineering and industrial design creates a powerful battery charger in a tiny footprint. It uses high-frequency switch-mode technology to efficiently convert A/C power into safe D/C power for battery charging. The G3500's onboard microcomputer precisely controls the charging to minimize power loss to create an incredibly compact form factor.

More ways to charge.

The possibilities are endless.

Permanently mount eyelet connectors on multiple vehicles to make hard-to-access batteries easy to charge. Charge directly through the 12V auxiliary or OBDII port from inside a vehicle, or just extend the reach of your accessories. Whatever the case may be, our interchangeable X-Connect battery accessories create a reliable weatherproof connection that not only provides maximum current flow, but also allows for fast and easy accessory changes.View All Battery Charger Accessories
